'Soul' in the Bible

“Tell me, O you whom my soul loves,Where do you pasture your flock,Where do you make it lie down at noon?For why should I be like one who veils herselfBeside the flocks of your companions?”

“On my bed night after night I sought himWhom my soul loves;I sought him but did not find him.

‘I must arise now and go about the city;In the streets and in the squaresI must seek him whom my soul loves.’I sought him but did not find him.

“The watchmen who make the rounds in the city found me,And I said, ‘Have you seen him whom my soul loves?’

“Scarcely had I left themWhen I found him whom my soul loves;I held on to him and would not let him goUntil I had brought him to my mother’s house,And into the room of her who conceived me.”

“Before I was aware, my soul set meOver the chariots of my noble people.”
